Psy 240

Doctors and psychologists have found that children who are malnourished are less cognitively developed compared to children who eat regular, healthy meals (Brooks-Gunn & Duncan, 1997). For example, children who live in extreme poverty who are malnourished have an IQ of u=94, o = 15 . To promote better brain development, several Head Start pre-schools in low-income neighborhoods began offering healthy breakfasts for their children. To see if this program improved IQ, a random sample of 100 4-year olds were tested after one year in the breakfast program. Their average IQ was M = 98
